Emulsion scoop coaters are important tools for proper emulsion activity. It is necessary have tool when it comes to coating of direct liquid emulsions. It is used for the application of a smooth and even emulsion coat. A good scoop coater should be properly designed to allow for easy grip, application and cleanup. Most Emulsion Scoop Coater is made of durable aluminum with an additional plastic end cap that provides guidance. It is comes as a package with standardized plastic sleeves for protection against banging the application on the edges. This plastic protection often reduces emulsion streaks occurring on both sides of the screen. This way, the emulsion is saved and the reclaim time reduced. It is usually dual edged, having both a thick and thin end. This design permits the coating emulsion on the screen to be either thick or thin. Each coat is preferred at different mesh sizes. The thinner screen coat is appreciate on the higher mesh counts of about two hundred half tones and four color process fine details. The thicker coat on the other hand is used mostly for spot colors on lower mesh counts, usually below two hundred. Emulsion scoop coaters are usually measured according to the size of inches and this is also how they differ in prices. The four-inch scoop coater has a small screen and a hat. The sixteen-inch scoop coater has manual press screens and the nineteen-inch scoop coater has an automatic press screen. The bigger the emulsion scoop coater is, the more expensive it costs. Screens in most cases are measured by their outside dimensions, are normally four inches frame, and mesh which should be uncoated to allow for printing to take place. This is only possible when the mesh can spread and stretch off contact. To coat, you should use a scoop coater that is wide enough to cover the entire emulsion width in a single pass. Screen makes usually prefer a double coat emulsion. This works in the sense that one coat covers the other on the screen substrate and the other is used on the flipped ink side.
